FS: Aerox Regulator, Cannula and Mask

[George Haeh]

Moving from an ASW-20 to a 27 with
automatic hookups left me with a smaller
oxygen cylinder and last year I ran out on a
couple flights. Then a couple weeks ago I
knocked my cylinder over breaking the
flowmeter - $62 at W&W; so decided to
bite the bullet and switch to Mountain
High.

The single outlet regulator with pressure
gauge + mask(unused) + Oxysaver
cannula add up a bit over $250.

$150 obo takes it.

Can you email me at Zen1960 at live bot com. I will spring for it. Looking to put on in my KA6CR.

public service announcement... this:

so far, appears less likely to fall apart in normal use vs the right angle flow controls

http://wingsandwheels.com/oxygen-equipment/aerox/cannula-masks/aerox-adjustable-flowmeter.html

still being sold at popular soaring supply houses. The right angle jobs seem to last about three wave camps. Mine broke on the ground, others have been less fortunate. The plastic flowmeter housing generally breaks just above the needle valve.

People still fly with manually adjusted oxygen systems? :-o

That's like flying with a mechanical vario (no audio).
It can be done but is it really in one's best interest to be constantly fiddling with things inside the cockpit?

[Jonathan St. Cloud]

Well, he'll if we are selling used oxygen equipment, I have two older Aerox flow meters, $35 takes both, I could probably throw in one or more of the "oxsaver" cannula. Moved to Moutain high years ago. Contact me privately.

Sure. I fly about ten flights a year with ox... and most of those to altitude where the MH system isn't really the preferred tool.

btw... "constantly fiddling" (in general) means "you're doing it wrong". :-o

Those cheaply made flow meters are for the birds. I bought medical
grade panel-mount flow meters for my Sinus (experimental) at 2/3 the
cost and they're far superior in materials and quality. If you don't
have panel space to mount one, you could lay it in your lap just like
the other one, though it's a bit more substantial. Here's a link to an
example: https://www.dwyer-inst.com/Product/Flow/VariableArea/SeriesOMA

The listed site says you can use the flow meter with any O2 system. That is wrong and could be dangerous. Do not use with a Mountain High system.

Dan, what flow rate is used for what altitude?

[Dan Marotta]

I don't recall exactly. I carried a pulse oximeter to keep tabs on O2
saturation. Take a look at this link:
http://www.c-f-c.com/gaslink/docs/abo4.htm
<http://www.c-f-c.com/gaslink/docs/abo4.htm> . Using that it appears
that 1 lpm/10,000' is the FAA recommended flow rate. Therefore, 1.8 lpm
at 18,000', but I'm certainly no expert and you'll have to make your own
choices.

The straight one you are showing appears to be the newer model from Aerox. If so, it is the one that they tested to -50 degrees and is made of a much better material than the second one you showed.

When I had mine broke in half changing over to a mask at 23,000 ft, I was in a world of hurt. I got down ok, and there is a little story to that, but not for now.

I talked to Aerox and told them they about killed me with their cheap product that was supposed to be aviation grade. They responded telling me that the clear one is fine for WARM conditions in a cockpit, but their new thicker one was tested to -50, and a heavier material that would hold up fine in wave conditions.

IF YOU HAVE THE OLD CLEAR ONE, THROW IT AWAY, AND GET THE NEW ONE FROM THE DIFFERENT MATERIAL. Or better yet put in in your freezer, then pull it out and snap it like a twig so you will never be tempted to use it again.

GET THE NEW ONE THAT IS BETTER MATERIAL, LIKE THE FIRST PHOTO.

I was 10 minutes away from an eastern Lennie in my 1-26. Glad I was not higher when it failed.

It's unfortunate that the Aerox flow meters are now limited to 25K, as they used to have a scale to 30K. The flow meter that Dan advocated appears to be a better choice if planning on exceeding 25K.

Be sure to use a mask above 18,000'.

I have two flow meters that are scaled to 30,000, if anyone wants them contact me off line on the reply privately button.

And have a plan B if you fly really high.
O2 systems are not infallible so a small handheld emergency backup O2 supply like the Mountain High Co-Pilot Portable is probably a good idea unless your glider is capable of descending at 20,000 feet per minute (200 knots vertical dive).
Time of useful consciousness at 30,000 feet could be as little as 1 minute.
